ABSTRACT:
A device for manufacturing loops of steel employed in continuous-operation presses to manufacture single-layer or multiple-layer webs of material. To equalize the tension in the ends of a strip before they are welded together to form a loop and to increase the strength of the weld, the strip (10) is laid over drums (2 and 3) and its ends secured in grippers (13) that travel across the drums' axes (4 and 5). The strip is tensioned to a prescribed tension. The tension is maintained while the ends (11 and 12) of the strip are secured by transverse tensioning arms. The tension is released by moving the movable axis to an operating distance. The strip is cut with a blade, the ends of the strip are ground parallel, and are welded together to form a loop.
